The Evolution of Pneumatic Foramina in Pterosaur Vertebrae
Anais da Academia Brasileira de Ciências, 2019 : Pterosaurs possess skeletal pneumatization, which can be assessed externally through the observation of pneumatic foramina. These foramina vary in position, shape, and number among taxa.

Egg shape changes at the theropod–bird transition, and a morphometric study of amniote eggs [PDF]
, 2014 The eggs of amniotes exhibit a remarkable variety of shapes, from spherical to elongate and from symmetrical to asymmetrical. We examine eggshell geometry in a diverse sample of fossil and living amniotes using geometric morphometrics and linear ...
